Question

我有一个设置表，可以存储各种租户设置：

CREATE TABLE `client_settings` (
  `key` varchar(255) DEFAULT NULL,
  `value` varchar(255) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

是否有一种简单的方法可以将映射器用于以下内容：

$mapper->get('key')

或

$mapper->set('key','value')

Answer 1

映射器中没有内置这样的东西。您必须为映射器创建映射器，这样做。我做了一个非常基本的例子：

class client_settings {
    private $mapper;

    function __construct() {
        $f3 = Base::instance();

        $mapper = new \sql\mapper($f3->get('DB'), 'client_settings');
    }

    function get($key) {
        $this->mapper->load('key = ?', $key);
        return $this->mapper->key;
    }

    function set($key, $value = '') {
        $this->mapper->load('key = ?', $key);
        $this->mapper->key = $value;
        $this->mapper->save();
    }
}

Answer 2

我接受了@sascha上面的答案，因为我喜欢模型中“外部”映射器的想法，但所提供的代码由于各种原因不起作用。根据他的建议，这就是我最终使用的内容：

class Settings {

    private $mapper;

    function exists($key){
        $this->mapper->load(array('`key` = ?', $key));
        return !$this->mapper->dry();
    }

    function get($key) {
        $this->mapper->load(array('`key` = ?', $key));
        return $this->mapper->get('value');
    }

    function set($key, $value = '') {
        $this->mapper->load(array('`key` = ?', $key));
        $this->mapper->set('key',$key);
        $this->mapper->set('value',$value);
        $this->mapper->save();
    }

    function __construct() {
        $this->mapper = new \DB\SQL\Mapper(\Base::instance()->get('DB'),'settings');
    }

}

使用键/值模式和Fat Free Framework Mapper
